TECHNICAL SPECIFICATIONS FOR GE - IS200ISBEH2A

IS200ISBEH2A is a ISbus Extender Board developed by GE. The GE Energy EX2100 Excitation Control System is a cutting-edge platform for generator excitation. Along with the transformers, this excitation system includes multiple controllers, power bridges, and a protection module. This board contains a DATEL DC/DC converter with an 18V to 36V input and a 5V output-1A. This part is identified as UWR 5/1000-D24 04127A612A. There are two fiber-optic connectors, two two-position terminal strips, and two male plugs labeled P1A and P1B on the board. The board is made up of three LEDs (two green and one amber) and eight integrated circuits. The board has the markings 94V-0 and FA/00.

IS200ISBEH2A FEATURES

  • The board encompasses a range of impressive features and components designed to facilitate efficient transmit/receive connectivity. Specifically engineered to seamlessly integrate with the Control Assembly Backplane's J11A local ISBus Interface Connector, this board serves as a critical interface for data transmission and reception.
  • One notable component of the board is the DATEL DC/DC converter, which boasts an extensive input voltage range spanning from 18V to 36V. This converter reliably generates a consistent output voltage of 5V, ensuring stable and regulated power supply to the board and its connected components.
  • The board showcases several connectors to facilitate easy and secure connections. Notably, there are two P1A and P1B plugs, which enable seamless integration with external devices. Additionally, two terminal strips, each equipped with two positions, are strategically positioned on opposite sides of the board, further enhancing connectivity options. The board also incorporates two fiber-optic connectors, labeled as R and T, which facilitate reliable transmission and reception of optical signals.
  • Four conduction sensors, denoted as E1 through E4, are present on the board, providing essential monitoring capabilities. These sensors enable the board to accurately detect and respond to specific operational conditions or events, ensuring optimal performance and system integrity.
  • Additionally, a three-position jumper switch is included on the board, enabling operators to configure specific settings or functionalities as per their requirements.
  • The "JP1-Interlock Bypass" information box prominently displayed on the board provides valuable guidance regarding the operation of the interlock bypass feature. This feature allows for the seamless transition between bypassed and unbypassed states, with the corresponding settings indicated as 1-2 for unbypassed and 2-3 for bypassed, enhancing operational flexibility.
  • To facilitate effective visual feedback and status monitoring, the board is equipped with three Light Emitting Diodes (LEDs) that serve as indicators of various system states or conditions. Additionally, eight integrated circuits on the board contribute to its complex functionality, enabling advanced processing and control capabilities.
  • Furthermore, the board incorporates a variety of passive electronic components such as resistors, diodes, and capacitors. These components play vital roles in supporting circuitry, facilitating signal conditioning, voltage regulation, and overall stability.
  • Collectively, the board's array of features, connectors, sensors, switches, and electronic components provide a robust foundation for reliable data transmission, control, and monitoring within the specified system.

    • CONTROL POWER SUPPLIES

  • Power Sources: The EPDM is supplied by three power sources: a 125 V DC source and one or two 115 V AC sources. These sources provide the primary electrical inputs to the EPDM.
  • AC/DC Converter (DACA):The 115 V AC source, if present, is passed through an AC/DC converter (DACA) as depicted in Figure 2-8. The DACA converts the AC input to a regulated 125 V DC output. This regulated DC output is then combined with the existing 125 V DC source to create a common DC bus.
  • Common DC Bus: The DC output from the DACA and the original 125 V DC source are diode-coupled together to create a common DC bus. The common DC bus serves as the main power distribution pathway, feeding power to the control modules and gate pulse amplifier boards in the system.
  • Fused Outputs: The EPDM generates fused outputs from the common DC bus to supply power to various components within the system. These fused outputs include power feeds to the EGPA (Excitation Gate Pulse Amplifier) boards, EXTB (Exciter Terminal Block), and the Exciter Power Backplane (EPBP). The use of fuses ensures protection against overcurrent and short circuits, safeguarding the components from potential damage.
  • LED Indication and On/Off Isolation Switches: Each fused output from the EPDM is equipped with LED indicators and on/off isolation switches. The LED indicators provide visual feedback, allowing operators to monitor the status of each power output. The on/off isolation switches allow for manual control over the power supply to specific components, providing a means to enable or disable power as needed.
  • Exciter Power Supply Modules (EPSM): The EPBP backplane can accommodate up to three Exciter Power Supply Modules (EPSM). These modules are responsible for generating specific supply voltages required for the controllers. They are fed with the regulated 125 V DC from the EPDM and produce logic-level power outputs of +5 V DC, ±15 V DC, and +24 V DC. These supply voltages are crucial for the operation of the control modules and gate pulse amplifier boards, ensuring proper logic-level signaling and functionality.
